 1.DN-GZW series new type explosion and combustion proof flame arrester is suitable for kind A oil in which the flash point of medium is below 28 ℃ and crude oil, gasoline, kerosene, toluene, high-gravity oil in which the flash point is below 60 ℃. Its function is to permit inflammable gas passing. It possesses resisting and asphyxy function to flame. The limit fire retardant speed is 435m/s.
2.The property of fire retardant of this new type explosion and combustion proof flame arrester is determined by National University of Defense Technology, Tianjin Research Institute of Fire Fighting Science and is conformity with the regulation specified in GB 13347:《The quenching ability of flame arrester and its test method for petroleum gas piping systems》(GJXJ [2003] No. 42).。
3.This new type flame arrester possesses reasonable structure and is beautiful in pattern. Its case may be made of carbon steel, cast steel, aluminum alloy and stainless steel, etc. the core of fire retardant layer is made of stainless steel. It has many advantage properties, e.g. strong in corrosion resistant property, combustion resist, explosion retardant, etc. it is a replacement product for ripple net pattern type flame arrester.
4.This flame arrester can be used independently and together with breather valve. It is suitable for different fields, e.g. transporting flammable gas pipeline, torch system, oil/gas recovery system,gas analytical system and coal mine gas discharge system, etc.
Nominal pressure:1.6MPa
